Yes, a real story from NPR details how researchers in Israel are teaching goldfish to operate a fish tank on wheels. This team is looking to explore whether animals' ability to navigate are present only in their native environments or if their abilities exist everywhere.
Researchers created the "fish operated vehicle," a set of wheels under the goldfish tank that uses an intricate camera system to record and translate a fish's movements into navigational directions. The FOV changes its position based on the fish's movement characteristics, location and orientation in the water tank.NPR
While this sounds like a silly experiment that doesn't hold a lot of real-world merits, there is actually a video on that NPR article showing the motorized fishbowl in action. Maybe someday in the future, your fish can walk itself over to where you keep the food and feed itself.
